Which type of rock is gold found in?
The abundance of gold in crustal rocks is an important constraint on the formation of gold deposits. Gold concentrations in unmineralised igneous, sedimentary and metamorphic rocks range from 0·05 to 20 ppb with average concentrations commonly between 0·5 and 5 ppb.

While the Welcome Stranger is the largest gold nugget ever discovered, the single biggest gold specimen ever found is the Holtermann. Dug up in October 1872 by German miner Bernhardt Holtermann at Hill End in New South Wales, it was crushed, and the gold extracted.
How do they get gold out of rock?
You can extract gold from quartz rock that contains veins of gold. However, you’ll need to crush the quartz to access the gold. Use a sledgehammer to break the rock into smaller pieces. Lift the sledgehammer into the air, then swing it down onto the rock as hard as you can.
